Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How to call a function from level blueprint inside c++?

Hello!

How to call a function from level blueprint inside c++?

I have function in level blueprint: alt text

And C++ code:

.h

     UFUNCTION(BlueprintCallable, Category = Menu)
     static void CallTimeUpMenuFunction(AActor* actor);

.cpp

 void AGHTimer::TimerBody()
 {
     AGHTimer::Time--;
 
     if (AGHTimer::Time == 0)
     {
         CallTimeUpMenuFunction(this);        
     }
 }
 
 void AGHTimer::CallTimeUpMenuFunction(AActor* actor)
 {
 
     FOutputDeviceNull ar;
     actor->GetLevel()->CallFunctionByNameWithArguments(TEXT("ShowTimeUpMenu"), ar, NULL, true);
 }


And this doesn't work. Menu not showing :( What is the problem?

In case you are still looking for an answer to this question; you have to call the function in the levelscriptactor within the level, not the level itself. Something like this:

 actor->GetLevel()->GetLevelScriptActor()->CallFunctionByNameWithArguments(TEXT("ShowTimeUpMenu"), ar, NULL, true);
